COMBING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 466,227, dated December29, 1891.

Application filed May 12,1891. Serial No. 392,520. (No model.) Patentedin England June 1, 1889, No. 9,082.

To all whom it may concern.-

Be it known that we, MIC AEL FIRTH and J OSEPH ROBERTSHAW, subjects ofthe Queen of Great Britain and Ireland,residing at Bradford, in thecounty of York, England, have invented certain Improvements inOombing-Machines, (for which we have obtained Letters Patent in England,No. 9,082, dated June 1, 1889,) of which the followingis aspecification. The object of our invention is to obviate the liabilityof fibers collecting around and forming a lap upon either of thedrawingoif rollers mounted near each small circular comb, which oncoming in contact with the [5 pins of the adjacent comb-circle ben ds,breaks, or otherwise damages them to such an extent as to render themuseless for the proper and eifectual clearing of the fiber, and also byour combination to be enabled to dispense with the revolving funnelshitherto mounted near the said drawing-off rollers and near the centerof the machine by which the several slivers are collected and combined,and thereby to prevent some of the fibers being twisted 2 5 around orlaid across the remaining portion of the sliver, thus producingstraighter and more valuable cleared fiber or top.

In the drawings, Figure 1 represents a diagram plan of the comb-circlesand drawing- 0 01f rollers of a Nobles combing-machine arrangedaccording to our invention. Fig. 2 is a detail plan of the four centerrollers; Fig. 3, a sectional detail of one of the center rollers, andFig. at detail views of an arm for 5 traversing the additional endlessaprons.

The drawing-off rollers A and B and the stretching-rollers O and D oneach side of the machine are mounted and operated somewhat in the usualmanner; but in addition to the main endless aprons E, working around therespective drawing-01f rollers B for removing the sliver or clearedfiber from the adjacent small comb-circles F or F, we place an auxiliaryendless apron G around the other roller B of each pair and upon therespective additional stretching-rollers H and H mounted by preferenceupon a circular plate J, secured near the center of the machine.

The circular plate J is secured to the crossplate K of the machine. Therollers H, H

and 1-1 mounted on the circular plate J, are adjustable in the directionof the respective arrows in slots (see Fig. 2) cut in the said plate inorder to admit of regulation to suit the varying thicknesses of theendless aprons. 5 5 The rollers 1-1" H H are adjustable in the slots bythe screws which connect such rollers with the circular plate J, as willbe obvious by reference to Fig. 2.

The rollers 11 and H of one series and H and H of the other seriesare'so placed on the circular plate J as to allow the respective endlessaprons G to run in contact with the other or ordinary aprons E. Theendless aprons E and L run in contact,as hitherto, convey in thedirection of the arrows the slivers drawn from the large circle at M M.The slivers drawn from the small circles at N N pass along with thebefore-mentioned slivers between the aprons G and E toward the center ofthe machine, where all are combined on passing between the rollers H andH The slivers drawn from the large and small circles and combined at ornear the center of the machine in the manner described maybe conveyedtherefrom in the direction shown at Z, thus dispensing with the usualrevolving funnels about the center of the machine and preventing thefiber coming in actual contact with the drawing-oft rollers, therebyrender- 8o ing it impossible to lap around the same and damage thecomb-pins of the small circles.

The rollers upon plate J are mounted upon a central spindle S, having acollar Pformed thereon near the bottom somewhat larger in 8 5' diameterthan the spindle and a similar collar attached by a screw at the top.Each roller is recessed at the ends to such diameter as to correspondwith the collars, which form the bearing-surface, and by which arrange-9o ment loose fiber is not so liable to lap around the ends of therollers, as is the case with rollers mounted in the ordinary manner.

The stretching or carrying rollers O of each series are mounted tothetables T of any ordinary traversing apparatus in a similar mannor ashitherto, and in order that the additional endless aprons G may betraversed at the same time and in the same direction we attach to eachroller-bracket U an arm V, I00
